Myths, Legends & Ongoing Debates:
138/150/180/200 vocal overdubs: Not even close...
Edited down from a seven-minute-long version: It was always meant to be 5:55.
First video ever: Not even close...
John on backing vocals: Granted, the 1975 video and the 2018 biopic show him there, but that had nothing to do with what actually happened...
Played 14 times by Kenny Everett: It was four times, not four-teen.
Recorded on sixteen-track: Twenty-four, actually.
Recordings Having Begun on the 24th of August 1975: By the 18th of August they'd already worked on three tracks at least, and by the 22nd a rough mix of 'Bo Rhap' had already been played.
Wessex Studios Having Been Used: The band used Wessex for the previous record (Sheer Heart Attack) and for both of which came afterwards (A Day at the Races and News of the World), but not for A Night at the Opera since it was undergoing refurbishment after having changed owners.
